Since all new bins for 750 have freezing and rebooting problem you are better off in converting the 750 into 700. This can be done very easily. Open the case and disconnect the card reader. Then load a working 700 bin on to the 750 and you are done. If the bin does not load then just reboot the 750 and start the download before the ird has fully booted. It will take the download. Enjoy
